There’s been a lot of talk about automakers posting unrealistic fuel consumption and CO2 emission figures lately, with customers and various agencies reporting relevant discrepancies between official and actual numbers.
And a recent study conducted by the International Council of Clean Transportation (ICCT) could swell the already heated discussion even more, after reporting an average discordance in CO2 emissions of almost 25 percent in 2011.
According to the ICCT, German car makers had the biggest dissimilarity, with BMW, Opel, Audi and Mercedes-Benz publishing between 26 and almost 30 percent lower figures than what was found during actual use. At the other end of the table, Toyota and Citroen posted 15 percent lower numbers, while Citroen and Renault declared almost 20 percent less CO2 emissions.
Equally worrying is the fact that these values increased from less than 10 percent to about 25 percent in ten years. “Whereas in 2001 the average CO2 emission level for new cars in the EU was 168 g/km, and the discrepancy according to spritmonitor.de data was 7 percent, the corresponding
figures were 138 g/km and 23 percent in 2011. That is, while in every instance the CO2 emission level has decreased over the past ten years according to the data examined, the gap for each manufacturer has also widened, resulting in smaller real-world CO2 reductions than one would expect at first sight,” the study says.
